Z1 MyCrypt is NOT a standalone application.

The Z1 MyCrypt app is an email client for Z1 server products from Zertificon, which additionally allows you to securely send large email attachments. In order to use the security features of this app, a licensed Z1 server product is necessary – this needs to be purchased separately.

Please do not rate this app if you do not have any Z1 server products!

Together with Z1 SecureMail End2End, Z1 MyCrypt enables user friendly end-to-end encryption. By using organizational End2End it provides instant end-to-end email encryption with external business partners. With a Z1 SecureHub license, encrypted secure large file transfer is also possible directly from the app.


The recipient does not need any Z1 Software to exchange secure mails with a Z1 user.
